Variable error and cannot convert to boolean error

Question

So I’ve bolded were the errors are happening but I don’t understand why they are happening. It doesn’t make sense to me.

    for(int i = 1; i < Array.getLength(purchases);i++)
    {
        System.out.print("\n");
        System.out.print("Enter a price for item #"+i+": $");
        double temp3=input.nextDouble();
        double price=temp3;

            if(price=>0) **<==it wont let me have both = and >**
            {
                total=total+price;
                double temp1=total*100;
                int temp2=(int)temp1;
                total=temp2/100.0;
        System.out.print("That was $"+price+". Your total is $"+total);
            }
       else(price==0) **<=="The left-hand side of an assignment must be a variable"**
            {

            }
    }

You cannot use bold with code formatting, now the code is messed up by formatting — Tony Rad

if(price=>0)

This should be: -

if(price >= 0)

Note the order of > and =. > comes first.

And also: - else(price==0) should just be else, you don't need to add a condition in your else.

your greater than or equal to ordering is wrong.

if(price=>0)

should be

if(price>=0)

the correct ordering is to use >=

 else(price==0)

should be

 else if(price<0) //should be less than zero , because you are already checking if price is >=0 in your if.

or just else would suffice

nested if-else syntax:

  if(somecond){

   }
   else if(somecond){
    }
   else{ // you don't mention any condition for else, as it would be the last condition.

    }

Note that, your else if condition is already covered in your if. Just else would work.

@GanGnaM.. Well, in that case, your else if will never get executed. It tests for condition ==, and your if already has a condition >= which will itself check for ==.

So, either it should be else if(price < 0) which seems useless, so just else.

@RohitJain i just realised, else should check if price is lessthan 0 .as he's already checking in if price >=0. :P

In java, "greater than or equal to" is >=. Also, for the second error, you should have "else if", not just "else."
